SPECIFICATION formingpart of Letters Patent No. 661,134, dated November 6, 1900.

Application filed July 28, 1900l Serial No. 25,120. (No model.)

To all whom it may concern:

Be it.- known that I, ABRAHAM L. YEARIAN, a citizen of the United States, residing at St. rAnthony, in the county of Fremont and State of Idaho, have invented certain new and useful Improvements in Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itv ap- 1o pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the class of stoves which are especially adapted for burning wood fuel, the object of the invention being the production of a stove of simple and inexpensive construction possessing advantages in point of economy in zo fuel, comparatively large heating capacity, land uniform heat radiation throughout the stove-body.

Other advantages peculiar to my improved stove appear in the following description, which is directed to the details of construction and operation, and in connection with such description attention is called to the -accompanying drawings, in which- Figure l is a perspective view of a stove 3o embodying my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a sectional view on line, 3 3 of Fig. 2.

Referring to the said drawings by letter, A denotes the stove-casing, which is preferably of elliptical form in horizontal section and which has a bottom plate A', from which depend supporting-legs b b, and a top A2, centrally of which is an opening over which is removably fitted a cap or cover C. The top 4o is preferably provided around the opening with a fiange a to support the cover C, and also a lid c, upon which may be placed vessels the contents of which are to be cooked or warmed. A portion of the top A2 is of arch form in crosssection, as shown, and said top is preferably of cast metal, though the body of the casing, as well as a lining a therefor, may be of sheet metal. The'top and bottom plates are perforated at equidistant points 5o near the outer edge and air-pipes D D eX- tend between said apertures, lwhereby vertical air-passages are provided to promote circulation of the air in the apartment containing the stove. These air-pipes have no communication with theinterior of the Stove. Bolts e e are preferably employed to secure the parts of the stove together.

F denotes the combustion-chamber, which consists of an inner casing preferably of the same form in cross-section as the outer cas- 6o ing, but of less dimension than the. latter, whereby a space is provided for the accommodation of the air-pipes and also for the passage of the products of combustion, as will presently appear. The inner casing is l elevated to provide aspace between it and the bottom plate A'. The bottom platef of the inner casing is imperforate; but the sides fl, which extend above the horizontal center of the stove, are provided with numerous per- 7o forations or openings]c2 f2 in a number of planes and extending entirely around said sides. The lower portieri of the sidesf is without these perforations; but at f3 thereis provided a draftinlet, to which is connected an air-pipe g, leading upward through the casing-top A2, where a draft-regulator in the shape of a pivoted plate g is provided. Centrally of the bottom plate A is an openinga?, from which leads the-smoke-pipe H. This 8o pipe preferably extends upward, and close to one side of the casing A and near the top of the latter is an opening CL3, from which leads a branch h of the stovepipe. In the branch is a damper h', which when open affordsadi- 85 rect draft, this being desirable in starting a fire. The pipe H is provided with a downdraft-damper h2, which is closed when a direct draft is desirable, or, if preferred, both dampers may be opened at the same time to 9o produce a direct and a down draft. Handholes are provided in the base of the stove 'and in the smoke-pipe where it joinsthe plate A,which holes are covered by platesic".

In practice the fuel is introduced through the openingin the top A and the fire is started, preferably, by the use of the direct draft. When the dampers are adjusted to obtain a downdraft, the air which is admitted at the inlet f3 enters the body of the fuel, and the roo products risingtherefrom pass through the openings f2 and over the top of the inner casing and thence downwardly between the casing sides and around the ai 1-pipes and finally center at the outlet a2 below the inner casing and pass ot'f through the smoke-pipe. ln this man ner not only is the hentdistrbuted evenly around the casing, but by reason of the openings f2 the flames and products are directed to heat the stove from bottom to top, whereby the heat radiation is rendered uniform throughout the stove-body.

The means employed for breaking up the flames und products prevent any great heat being centered on any particular part of the stove, so that the structure is rendered very durable.

The stove is simply constructed, may be cheaply made, and is highly etiicient in op eration.

I claim as my inventionl. In a stove of the class described, the combination of' an outer closed casing having an inlet for air in its upper end and an outlet for the products of combustion centrally in its base, an inner casing supported away from the base and sides of the outer casing said inner casingr having a closed base, au open lop, a plurality7 of openings in the upper portion o' its wall, and an air-draft inlet in its lower portion connected to the air-inlet in the outer casing.

2. Ina stoveof theclass described, the combination of an outer closed casing); having an inlet for air in its upper end and an outlet for the products 4of combustion centrally in its base, an inner casing supported away from the base and sides of the outer casing, said inner casing havingtgl a closed base, an open top, a plurality of openings in the upper portion of its Wall, and an air-draft inlet in its lower portion connected to the :tir-inlet in the outer casing, and air-pipes between the casing-walls and extending between openingsin the top and bottom of the outer casing.

3. In a stove of the class described, the cornbination of an outer casing having,` an inlet in its top for air and an outlet in its bottom for the products of combustion, a smoke-pipe leading from the bottom opening, a directdraft opening in the top of the casing connected with the smoke-pipe, a damper for the pipe and a damper for the directdraft opening, an inner casingl supported in the outer casingr away from the base and sides, en aix inlet in the base of the inner casing, a pipe connecting` said air-inlet. with the inlet in the outercnsingtop, and aregulatorfor said pipe.

ln testimony whereof:` I aflix my signature in presence of two witnesses.
